N'afọ 1880, onye America mepụtara ihe Edison mepụtara nnukwu ihe eji emepụta DC nke a kpọrọ "The Colossus", nke e gosipụtara na Paris Exposition na 1881.
Edison bụ nna nke Direct Current
N'otu oge ahụ, mmepe nke moto eletriki na-aga n'ihu. Generator na moto bụ ọrụ abụọ dị iche iche nke otu igwe ahụ. Iji ya dị ka ngwaọrụ mmepụta ugbu a bụ jenerato, iji ya dị ka ngwaọrụ inye ọkụ bụ moto.
E gosipụtara ụkpụrụ a nke igwe eletriki a na-agbanwe agbanwe site na mberede na 1873. N'ihe ngosi ụlọ ọrụ mmepụta ihe na Vienna n'afọ a, otu onye ọrụ mere mmejọ wee jikọọ waya na jenerato Gram na-agba ọsọ. A chọpụtara na rotor nke jenerato ahụ gbanwere ntụziaka wee gaa n'akụkụ nke ọzọ ozugbo. Ụzọ ahụ na-atụgharị ma ghọọ moto. Kemgbe ahụ, ndị mmadụ aghọtala na enwere ike iji moto DC dị ka jenerato na ihe na-agbanwe agbanwe nke moto ahụ. Nchọpụta a a na-atụghị anya ya enweela mmetụta dị ukwuu na imewe na mmepụta nke moto ahụ.
Site na mmepe nke mmepụta ike na teknụzụ inye ike, nhazi na mmepụta nke moto na-aghọwanye nke zuru oke. Ka ọ na-erule afọ 1890, moto DC nwere ihe niile bụ isi nke moto DC nke oge a. Ọ bụ ezie na ejirila moto DC mee ihe nke ukwuu ma mepụta uru akụ na ụba dị ukwuu na ngwa ahụ, adịghị ike nke ya na-egbochi mmepe ya ọzọ. Ya bụ, ọ nweghị ike idozi nnyefe ike dị anya, ọ nweghịkwa ike idozi nsogbu nke mgbanwe voltaji, yabụ moto AC etoola ngwa ngwa.
N'oge a, injin abụọ na injin atọ pụtara otu otu. Na 1885, onye ọkà mmụta sayensị Itali bụ́ Galileo Ferraris tụrụ aro ụkpụrụ nke ịgbagharị magnetic field wee mepụta ụdị moto asynchronous nke usoro abụọ. Na 1886, Nikola Tesla, onye kwagara United States, mekwara moto asynchronous nke usoro abụọ. Na 1888, onye injinia eletriki Russia bụ́ Dolivo Dobrovolsky mere moto AC otu squirrel nke usoro atọ. Nnyocha na mmepe nke moto AC, karịsịa mmepe nke moto AC nke usoro atọ, emeela ka ọnọdụ maka nnyefe ike dị anya, ma n'otu oge ahụ emeela ka teknụzụ eletriki ka mma ruo n'ọkwa ọhụrụ.
Tesla, nna nke alternating current
N'ihe dị ka afọ 1880, ndị Britain Ferranti mere ka alternator ahụ ka mma ma tụọ aro echiche nke nnyefe AC dị elu. Na 1882, Gordon na England mepụtara nnukwu alternator nke nwere usoro abụọ. Na 1882, onye France bụ Gorand na onye Bekee bụ John Gibbs nwetara patent nke "Ụzọ nkesa ọkụ na ike", ma mepụta transformer mbụ nke nwere uru bara uru. Mgbe e mesịrị, Westinghouse mezigharịrị owuwu nke transformer Gibbs, mee ka ọ bụrụ transformer nwere arụmọrụ ọgbara ọhụrụ. Na 1891, Blow mere transformer nke nwere mmanụ dị elu na Switzerland, ma mesịa mepụta nnukwu transformer dị elu. Transformer AC dị elu nke nwere voltaji dị elu emeela nnukwu ọganihu n'ihi mmezi na-aga n'ihu nke transformers.
Mgbe ihe karịrị afọ 100 nke mmepe gasịrị, ozizi nke moto ahụ n'onwe ya etoola nke ọma. Agbanyeghị, site na mmepe nke injinịa eletriki, sayensị kọmputa na teknụzụ njikwa, mmepe nke moto ahụ abanyela n'ọkwa ọhụrụ. N'ime ha, mmepe nke moto AC ọsọ bụ ihe kacha adọrọ adọrọ, mana a kabeghị ya ma tinye ya n'ọrụ ruo ogologo oge n'ihi na ihe ndị mejupụtara sekit na nkeji ntụgharị rotary na-emezu ya, arụmọrụ njikwa adịghịkwa mma dịka nke iwu ọsọ DC.
Mgbe afọ 1970 gasịrị, mgbe ewebatara ihe mgbanwe eletrọniki ike, nsogbu nke ibelata akụrụngwa, ibelata nha, ibelata ọnụ ahịa, imeziwanye arụmọrụ, na iwepụ mkpọtụ bịara jiri nwayọọ nwayọọ dozie, iwu ọsọ AC wee nweta ọganihu. Mgbe emepụtara njikwa vektọ, arụmọrụ kwụsiri ike na nke na-agbanwe agbanwe nke sistemụ njikwa ọsọ AC ka mma. Mgbe ejiri njikwa kọmputa micro, a na-eji ngwanrọ eme ihe iji hazie sekit ngwaike, si otú a na-ebelata ọnụ ahịa ma na-eme ka ntụkwasị obi dịkwuo mma, ọ ga-ekwekwa omume ịghọta teknụzụ njikwa dị mgbagwoju anya karị. Ọganihu ngwa ngwa nke teknụzụ eletriki ike na teknụzụ njikwa kọmputa micro bụ ihe na-akpali maka mmelite na-aga n'ihu nke sistemụ njikwa ọsọ AC.
N'afọ ndị na-adịbeghị anya, site na mmepe ngwa ngwa nke ihe magnet ụwa na-adịgide adịgide na mmepe nke teknụzụ eletrọnịkị ike, injin magnet na-adịgide adịgide enweela nnukwu ọganihu. A na-eji injin na jenereta na-eji ihe magnet na-adịgide adịgide NdFeB eme ihe nke ukwuu, site na mkpali ụgbọ mmiri ruo na ọkpọkọ ọbara obi arụrụ arụ. A na-eji injin superconductor eme ihe maka mmepụta ike na mkpali nke ụgbọ oloko na ụgbọ mmiri maglev dị elu.
Site na ọganihu nke sayensị na teknụzụ, mmezi nke arụmọrụ nke ihe ndị e ji arụ ọrụ na mmezi nke usoro mmepụta, a na-emepụta moto ndị a site na ọtụtụ puku ụdị na nkọwapụta, ọkwa ike dị iche iche (site na nde watt ole na ole ruo ihe karịrị 1000MW), yana ọsọ sara mbara.
